How to fix null IMEI on Unisoc / Spreadtrum (SPD) devices - hovatek - 02-10-2014

Below is a step-by-step guide on how to fix null / invalid IMEI on a Spreadtrum Android device. Invalid IMEI could cause the phone to be unable to detect your SIM card's network meaning no calls, internet or USSD code (to check your account balance).

What causes null / invalid IMEI


Null IMEI is as a result of corrupted NVRAM partition. This can happen when you flash an incompatible firmware (be it stock or custom) or make any change which affects the NVRAM partition.

If your device also has an unknown Baseband then resolve that first (by flashing the pac file) before attempting to fix the null IMEI else IMEI write attempts will keep failing.

Important Notice
  • None of these tools generates an IMEI for you. They only write or (at best) crosscheck what IMEI you supply
  • You can find your device's IMEI at the back of the device or on its carton
  • This guide only explains how to write IMEI to your Spreadtrum phone. You are entirely responsible for what IMEI you write
  • If you have an unknown Baseband (Settings > About > Baseband) then consider flashing the stock ROM first to regain Baseband before going ahead to fix IMEI
  • Should you decide to opt for a dongle / box approach then ensure you have the hardware else opt for a loader version (if one is available)
